Bolam's mouse

Bolam's mouse, Pseudomys bolami, is a nocturnal, burrowing rodent in the family Muridae that lives in the semi arid and southern arid regions of Australia. It is about the size of a house mouse but slimmer, with larger eyes, feet and ears and a longer tail, and adults weigh between 9 and 16 grams. It can survive by extracting water from seeds alone and produces highly concentrated urine. The diet is omnivorous, mixing seed, plant material, invertebrates and fungus, with the balance shifting through the seasons. It was first described in 1932 as a subspecies of the sandy inland mouse and was raised to a full species in 1984. Land clearing and predation by introduced foxes and cats have shrunk its range.
